| Abstract: |
| Rice tartary buckwheat with thin shell（ Fagopyrum. tataricum G.） and perennial tartary buckwheat
（F. tatari-cymosum Chen） are called as the new-type tartary buckwheat and there is little reports available
about them. In this study the grain characters and quality in 5 rice tartary buckwheat varieties and 3 perennial
tartary buckwheat varieties were analyzed with Jiujiang Kuqiao as the control. The results showed that：there are
significant differences in grain characters and quality of these varieties. The contents of total flavonoids，crude
protein，total starch，and pullulan in rice tartary buckwheat are significantly higher than those of Jiujiang kuqiao
（CK），however，the pullulan in the F. tatari-cymosum was significantly higher than that of Jiujiang kuqiao
（CK）. As comparison with perennial tartary buckwheat，rice tartary buckwheat has higher the content of total
flavonoids，amylopectin and 50 mL VM. Correlation analysis showed that there is no significant correlation between
the total flavonoid and other indexes. There are，however，significant positive correlationships between SW and 100
GKW，100 GSW . The pullulan content has significantly positive correlation with total starch content. Moreover，
partial correlation also showed that there was significant positive correlation between the content of crude protein and
total starch，SW，100 GKW at different levels. |
